Channel energy - alignment channel feat

[Blake Duffey]

the feat description says: Benefit: Instead of its normal effect, you can choose to have your ability to channel energy heal or harm outsiders of the chosen alignment subtype. You must make this choice each time you channel energy. If you choose to heal or harm creatures of the chosen alignment subtype, your channel energy has no effect on other creatures. The amount of damage healed or dealt and the DC to halve the damage is otherwise unchanged.

My question - do you pick one (say evil) and you can choose to heal OR harm them?

Or do you pick an opposed pair (good/evil) - and can harm evil/heal good?

Based on the text, it seems like you pick one and can choose to harm/heal them per usage. Which seems little goofy to me. My paladin can choose 'evil' as the alignment, so I can harm them (that makes sense). But I can heal them if I choose?

Thanks

Yes, you could heal them. After all, you might need information from one that is in critical condition. Maybe you'll be taking the outsider to a legitimate authority to be punished for its crimes. There's always the possibility that you'll try to redeem one. Nothing wrong with the attempt to heal an evil outsider.

Based on the text (and our 'at the table' discussion last night) I can't disagree - but it seems to be 'wacky', since it is different than the standard channel.

Thanks for your input!
